Abstract
A locking system for coupling a first member including an aperture, and a second member having a receiving region is disclosed. The locking system comprises: (a) an interference element including (i) a first portion that fits within the aperture when the locking system couples the first member and the second member together, (ii) a second portion, wherein the first portion forms an angle with respect to the second portion, and (iii) a protrusion that extends into the receiving region when the locking system is in use; and (b) a locking element that engages the second portion of the interference element when the locking system is in use.

A locking system for coupling a first member including an aperture, and a second member having a receiving region, the locking system comprising:
- (a) an interference element including (i) a first portion that fits within the aperture of the first member when the locking system couples the first member and the second member together, (ii) a second portion, wherein the first portion forms an angle with respect to the second portion, and (iii) a protrusion that extends into the receiving region of the second member when the locking system is in use;
- and
- (b) a locking element that engages the second portion of the interference element when the locking system is in use.
An assembly comprising:
- a first member including an aperture;
- a second member having a receiving region and a recess;
- and
- a locking system that couples the first member to the second member, wherein the locking system comprises (a) an interference element including (i) a first portion disposed within the aperture of the first member, (ii) a second portion, wherein the first portion forms an angle with respect to the second portion, and (iii) a protrusion that extends into the receiving region of the second member, and (b) a locking element that engages the second portion of the interference element and that is in the recess.
An excavation bucket assembly comprising:
- a bucket body;
- and
- a plurality of tooth assemblies coupled to the bucket body, wherein each tooth assembly includes an adaptor including an aperture, a tooth having a receiving region, and a locking system that couples the first member to the second member, wherein the locking system comprises (a) an interference element including (i) a first portion disposed within the aperture of the first member, and (ii) a second portion, wherein the first portion forms an angle with respect to the second portion, and (iii) a protrusion that extends into the receiving region, and (b) a locking element that engages the second portion of the interference element.
